https://community.appian.com/discussions/f/general/6676/hi-folks-this-is-regarding-engine-checkpoints-it-is-my-understanding-thaHi Folks, This is regarding engine checkpoints. It is my understanding, that during checkpoints the gateways (which affected by the process) are temporary not available for processing. Now, if we have let&#39;s say a significant size and many gateways foren-USTelligent Community 12https://community.appian.com/thread/26371?ContentTypeID=1Thu, 14 Jan 2016 04:10:04 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:7f4dcdab-cf97-4ab2-859b-6f982ff32f41Tom RyanIt may also be helpful to review your policy for archiving/deleting old processes that are no longer needed. This could help to prevent the exec engines growing so large:<br /><br /><a href="https://forum.appian.com/suite/help/7.11/Data_Maintenance.html">forum.appian.com/.../Data_Maintenance.html</a><div style="clear:both;"></div>https://community.appian.com/thread/26370?ContentTypeID=1Thu, 14 Jan 2016 04:05:09 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:51ed588f-ded6-4d40-b51f-6377434e8648urilHello colleagues Thanks for your response. We have close to 20 Gb Kdb files (mostly exec), and growing. We can schedule it of course, like twice a day for each gateway. Right now it is not even scheduled, so Appian itself manage it (maybe that is why I see &quot;Warn Checkpointing recommended&quot; for all my Process-exec. <br />My point was even if scheduled, if we have increasing wave of transaction it still might come up. <br />Based on the answers so far, it seems make sense to schedule (as many times a day as needed for all or for each gateway, and don&#39;t worry those messages even if they come up from diagnostic/checkengine report.<div style="clear:both;"></div>https://community.appian.com/thread/26360?ContentTypeID=1Thu, 14 Jan 2016 02:41:24 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:720730c3-333b-494e-9fae-5e1cd50c8b42Tom RyanYou can most likely remove the complexity of monitoring for checkpointing needed messages and run a scheduled checkpoint as required, staggering the checkpoint for each engine to distribute load more evenly.

Only concern for us is scheduling nightly processes around these times if they are heavy on database transactions.<div style="clear:both;"></div>https://community.appian.com/thread/26330?ContentTypeID=1Wed, 13 Jan 2016 15:10:33 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:de23054c-f34e-473b-8cd1-459849381e00nathan.schmitzThe checkpoints are typically not a problem if you are following other best practices.
